Quick updates on Eddie’s car

Speaking to Eddie recently he has no informed me that he’d like the car to be a two-seater, which means it’ll be much longer. This also then requires completely different aero off of the front wing, and also because the car will be so much longer, the weight distribution will be miles out, impairing the handling in slow speed corners. Also we won’t be able to run as much rake in the set up of the suspension as the front wing would then scrape on the ground. This means that the suspension will have to be easily adjustable for road and track use. Normal, higher ride-height for on the road with softer suspension, and then a lower ride height, with more rake and stiffer spring/damper settings for the track use. I’ve already started the amendments for the designs, but the front wing will be massively different. It will probably be a mixture of my Monaco spec wing and my Singapore spec wing.

Eddie’s car updates

Over the last few days I’ve been making small bodywork revisions and adding in some of the missing details to Eddie Ruskin’s car designs, namely the barge boards and having its own front wing now that allows more airflow to the barge boards. And that therefore means more air to the radiator inlets, and therefore it can have smaller inlets, and another product of that means smaller sidepod frontal area, less drag and more airflow to the rear of the car.

The front wing still keeps the ‘endplateless’ design, but rather than having 4 elements joining to the base plate, there is now only 3. The rearmost one being the largest one, and curving around at the same angle as the 4-element design. This creates a larger suction and stronger vortex. The front wing also has a much flatter main plane, but with a large squared off arch section. This creates a smaller, less powerful vortex, but the vanes underneath that curve also draw air upwards, splitting the airflow and stalling it above speeds of 120mph. This slightly reduces downforce in that area and creates a very strong vortex that is drawn around the front wheels, further reducing drag.

The car also now has VG’s on the leading edge of the sidepods, that draw the air out of the chimneys at a higher, more efficient rate. The design is exactly the same as the 2012 car VG’s, but there’s only one of them. As well as the chimneys there are now 4 slots in the top of the sidepods just to allow slightly improved cooling.

I’m still yet to do the floor, as trying to design a double diffuser on the 2008 designs will be very…. interesting. And difficult too with the exhaust blowing. Figuring out where to blow the exhausts will be difficult without wind tunnel testng. I’ll have to build this design and study the airflow in a home-made wind tunnel. After this test I could then make changes to parts of the car to improve airflow. And I can also see where the airflow goes that could be corrected with high speed exhaust gasses.

There is also a new nose, which is slightly higher, and slightly thinner. This gives more airflow to the floor of the car, more downforce and very slightly less drag.

Okay, that’s enough blabbing on, here is the updates.

2 door coupe.

This is the second of the two road cars I’ve designed in Microsoft PowerPoint. This one is a 2 door coupe. It has the same engine choices as the hatchback in my previous post, but the diesels are more powerful and there is also a choice of AMG engines, ranging from the 5.5L supercharged engine you get in the SLR McLaren to the 6.0 V12 Biturbo that you see in the S65 AMG. Also tuning kits for the engines would be available from Brabus, those nutcases you hear about on TopGear.

Styling is very aggressive from the front, and almost passive on the back. I also contemplated side exhausts, but come on… put the 1.8 petrol in and it’s just going to be pathetic. Same with the diesels. Who’d want a massive amount of smoke coming out of the sides of the car. It’s not the best looking car in the world, but I sure am proud of it. I  just need someone to design me some wheels for it… Any takers? Again, any feedback would be useful. Also suggestions as to what I should design next might come in handy.

Rear view. And yes those wide grey shapes at the bottom are the exhausts. This model would be fitted with the 5.5L SLR engine for which the exhausts would be needed for maximum airflow. Obviously smaller exhausts would be fitted to the standard non-AMG engines.

Remember feedback would be nice on ANY aspect of the car.

Road car.

Obviously I can’t just post blogs about PPT designed F1 cars, that would just be silly so of course, I have also designed a couple of road cars. One of them is still under the initial concept phase, but this one is nearing completion. Just a few small refinements to make, and the wheels to design. Obviously these are incredibly unlikely to be put into production, but I also have two lists of engines. One list of petrol SI engines, and one of Diesel CI engines) The smallest petrol is a 1.8, and the smallest diesel is a 1.7. Bearing in mind this is meant to be a sports coupe, although it might not LOOK very sporty, each petrol engine would be designed to produce max power at high RPM’s, and each diesel engine would have peak torque from 1,800 – 4000rpm

This is the side view of the car

This is the front view

This is the (unfinished) back.

Each model would have a ‘sports’ suspension pack option which increases steering response and lowers ride height by around 22mm. Every car has a 6 speed gearbox manual as standard with the larger engines (2.5) available with a CVT gearbox, or a semi-automatic gearbox with paddle shifters behind the steering wheel.

Below are the two lists of engines complete with some stats.

Remember this is all for fun and is purely fictional. Feedback on the design of the cars, and maybe new engine suggestions would be nice.
